CASK-PLANING MACHINE.

Specification of Letters Patent.

Serial No. 339,096.

T call whom it may concern:

Be it known that I, LUDWIG .DRExLER, citizen of Germany, residing at Munich, Bavaria, Germany, have invented certain new and useful Improvements in Cask-PlaninghIachines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

. This invention relates to machines for dressing the interior of casks by planing the same.

The object of the invention is a construction in which the cask may be readily placed in position to be operated upon or removed therefrom, and in which the tool is readily brought to bear upon the interior surface of the cask as may be required by the circumstances of the case.

With these objects in view the tool bearing shaft is so arranged as to be readily adjustable in a manner to bring the tool to bear in varying degrees upon different portions of the cask surface and to ermit the insertion and removal of the cask 1n its holders.

The invention as hereinafter more fully described and as particularly set out in the accom anying claims will be readily understood 'rorn an inspection of the accompanying drawings illustrating certain embodiments of the'invention, in which drawings Figure 1 is a longitudinal section through the machine and cask; Fig. 2 is a transverse section; Fig. 3 is an end elevation; Fig. 4 is a transverse section of a portion of the device on an enlarged scale; and Fig. 5 is a longitudinal section throu h Fig. 4.

Referring to the rawings in detail the tool a, carrying the blades 1) is mounted upon a tubular shaft 0 rotating in bearings d. In line with the shaft 0 is a stub shaft e of a diameter designed to fit the interior of the tool shaft 0 and likewise mounted in a bearing 1;. The bearings 11 and o are mounted upon pivots so as to permit of swinging latera ly in unison, the bearing o being pivoted to a standard carried by the machine frame and the bearing cl pivoted to standards formed on a slide to mounted on a carriage longitudinally movable on the machine frame by means of a screw spindle g driven by bevel gears g from the hand wheel S. Two cask holders h and i are provided, the former being carried by the carriage {4 and the latter fixed upon the machine ame,

The carriage f is' whereby the two holders h and 71 may by means of the hand wheel S be moved to and from each other to receive and grip the opposite ends of a cask within their central opening as shown in Fig. 1. These cask supports h and i are provided with peripheral teeth is and Z rotected by housings m and n, and the gears c and Z are arranged in gear with pinions o and a which pinions are so driven from a suitable source of power as to cause the cask holders to rotate in a direction opposite to that of the tool shaft whereby the tool blades 1) and the cask t rotate in opposite directions, the speed of the tool belng much greater than that of the cask.

To permit of lateral positioning of the tool relative to the cask interior the bearin s (Z are rovided with' a lever p which is held 111 any c esired position by a pawl r engaging a toothed sector g. A hand lever 2 connected with the slide w provides for the adjustment of the tool longitudinally of the cask by shifting of the slide w and with it the tool bearing shaft 0 in telescopic relation to .the stub shaft 6.

The operation of the device is as follows By the turning of the hand wheel S in the direction of the arrow in Fig. 1 the carriage f and the slide to with the cask holder h and the tool shaft and tool are moved bodily to the left away from the cask holder 1'. and the stub shaft e, whereupon the finished cask t is released by the holders and may be removed between the tool shaft 0 and stub shaft e which latter are separated in an axial direction.

An unfinished cask being placed by the reverse operation over the tool shaft, the

lation of the tool shaft and stub shaft being' resumed. The tool and the cask holders being set in motion, the operator by the roper adjustment of the hand levers Z and 1) rings the rotating tool a with its blades 1) into pro or relation with the oppositely rotating cas t so as to dress the interior of the cask. WVhen completed the cask is released and a new one inserted by a manipulation of the hand wheel S as previously described.

It 1s in some cases found desirable to retain of a greater thickness that stave which contains the bung hole or tapping hole so that the same shall not be too greatly weakened. In order to accomplish this result a device is provided as in Figs. 4 and 5 whereby the tool is automatically lifted from the cask surface at that point so as to cut to a less depth or leave untouched the particular stave. As shown, an abutment 0c is adj ustably mounted in the slot y of the cask holder h against which abutment an inclined arm w carried by the tool shaft 0 impinges at the proper moment whereby the laterally swinging tool shaft 0- and the tool are retracted and prevented from cutting the stave in question. To effect this the cask must obviously be placed in the holder with such stave in proper relation to the abutment x.

In order to cause the tool to swing back of its own accord when the hand lever p is released the bearings and 1) may be provided with counter weights, which have, however, been omitted to avoid confusion, the construction and application of such being well known.

Having thus described my invention what I claim as new is:

1. In a cask planing machine, the combination, with two cask holders relatively movable to and from each other, of a tool shaft comprising two parts, one associated with each of the holders and arranged to be coupled and uncoupled as the holders are moved to and fro from each other to grip and release the cask.

2'. In a cask planing machine, the combination, with two cask holders relatively movable to and from each other, of a tool shaft comprising two parts having telescopic relation one to the other, one of the parts associated with each of the holders, and means to move the cask holders and shaft members to and from each other, coupling and uncoupling the shaft members.

3. In a cask planing machine, the combination, with a frame, a cask end holder fixed thereon, and a stub shaft carried by the frame, of a carriage movable on the frame, a second cask end holder fixed on the carriage opposite the first holder, a tool shaft carried by the carriage in line with the stub shaft, and means to move the carriage longitudinally to cause the holders to grip a cask and to couple the shaft members.

4.
